1. Which intake have you all had great experience with? I am looking for a nice sound.
2. Which exhaust do you all suggest? I have looked into Q300 and Ark GriP. How is the cabin drone and how loud are these on the exterior?

Also, do you have to do anything with your CPU or electronics after these are installed? I also have a third party warranty for the next 5 years.

Thanks for any advice/suggestions.
